ROVING AND SLUBBING FRAME.

SPECIFICATION forming part of Letters Patent No. 302,631, dated July 29,1884-.

Application filed June 2, 1883. (No model.) Patented in EnglandoJuly 22,1881, No. 3,208, and in Germany January 30, 1582,

To all whom it may concern Be it known that J AMES HIGGINS, deceased,late of Salford, in the county of Lancaster, Great Britain, and THOMASSGI-IOFIELD WHIT- WORTH, of the same place, jointly invented certainImprovements relating to Roving and Slubbing Frames, of which thefollowing is a specification.

This invention is applicable to rovingframes in which the spindles areprovided with bevelwheels, and which are driven by wheels having obliqueteeth upon a driving-shaft arranged adjacent to the line or row ofspindles.

The invention consists in a novel combination,with a spindle, aspindle-step rail, and a copping-rail, of means for supporting anddriving the spindle, all as hereinafter de scribed, and set forth in theclaim.

In the accompanying drawings, Figure 1 is an elevation of a spindle anda vertical section of its appurtenances which embody the invention, andFig. 2 is a side elevation of two spindles and the means employed tooperate them.

Similar letters of reference designate corre-' sponding parts in bothfigures.

A designates the spindle, which is of the usual form, save atone partnear the lower end, where it has a square or polygonal portion, a.

B designates the bevel-wheel by which the spindle is driven. The lowerpart of its boss or hub b is formed square or polygonal, so as to fitupon the square or polygonal portion a of the spindle; but the upperpart of the boss or hub 11 is cylindric, so as to fit upon the cylindricportion of the spindle surmounting the square or polygonal portion a.The lower end of the boss or hub 11 of the bevelwheel B rests upon thefoot-step O, which is recessed at 0, so as to form an annular cavity forthe purpose of retaining any suitable lubricant. eral spindles gear intoand are driven by bevel-wheels D,with oblique teeth, secured upon theordinary spindle-driving shaft, D. The bevel-wheel B is kept in aposition for being driven by the cylindric portion of the spindlefitting the cylindric portion of the hub b,

The bevel-wheels B upon the sev-.

and by the lower end of said hub bearing against the foot-step G, andthe wheel is locked to the spindle by the square or polygonal portion ofits hub b, fitting the corre= sponding portion, a, of the spindle.

G is a tube in which the spindle is capable of revolving freely, and atthe lower end of the tube is a bridge or yoke, 0 which embraces thewheel B. The step 0, tube 0, and yoke C are all formed integralwith eachother, either by casting or forging. By this construction the exactalignment of the tube 0 and footstcp O is easily secured and maintained,and there is no binding action between the tube and the spindle,as therewould be if they were not in exact alignment. 6-

E designates the spindlestep rail ofa slubbing or roving frame, to whichis attached a bracket, E, which is secured to the rail by a screw, (1,so that it can turn therein. In the bracket is formed a cylindricaperture, c,within which the end of the footstep 0 fits, and wherein itis supported by a shoulder, c, on said foot-step. The portion of thestep 0 which enters the aperture 6 is formed barrel-shaped or convex ina vertical direction, for a purpose hereinafter stated.

F designates the copping-rail, to which a bracket, F, is secured byascrew, f, so that it may turn therein. The bracket F has a cylindricaperture, in which a bush, 9, is secured so by a set-screw, g. The tube(3 passes freely through the bush 9, and the bush slides on said tube asthe copping-rail F rises and falls. The aperture in the bush y is nottruly cylindric, but flares slightly from the middle toward each end. Iffrom any cause the copping-rail F should not rise and fall in aperfectly perpendicular direction in relation to the bracket E, the tube0 will be carried out of its perpendicular. The barrel-shaped orconvexed por- 0 tion of the foot-step 'O and the flaring portions of thebush 9, previously described,will permit the-copping-rail to rise andfall without a bind ing action being produced upon the bush 9'. The setscrew h, which serves to securethe foot- 5 step 0 in the bracket E,extends at right angles to or transversely to the length of thestep-rail E, and enters a hole formed in the v \Vhat is claimed, anddesired to be secured said rail and securing the foot-step bearing insaid bracket, the copping-rail and its bracket F F, and the bush g, madeflaring from the I5 middle toward each end, and receiving the tube 0,all substantially as herein described.
